 ### Plugin API changes
 
 The `PythonToolRequirementsBase` and `PythonToolBase` classes now have a new `help_short` field. Subclasses should now use `help_short` instead of the `help` field. The `help` field will be automatically generated using `help_short`, and will include the tool's default package version and provide instructions on how to override this version using a custom lockfile.
